ANTI-COUNTERFEIT RFID SEALING METHOD AND DEVICE THAT CHANGE INFORMATION UPON UNSEALING

摘要

An anti-counterfeit RFID sealing method that changes information upon unsealing: connecting a status module read interface to a RFID tag circuit; connecting the status module read interface to a status module circuit by means of an easily-broken connecting circuit; using the RFID tag circuit to read the status data stored in the status module circuit by means of the easily-broken connection circuit; then transmitting status information to an RFID reader according to the result of status module circuit reading. The present invention uses an RFID tag circuit to read the status of a status module circuit connected to the RFID tag circuit and to transmit the status information of normal or abnormal to an RFID reader according to the status of the status module circuit, thereby enabling the authentication of whether a seal has been broken while keeping the RFID tag circuit intact, and rendering RFID duplication counterfeit means ineffective. The RFID tags in the broken anti-counterfeit bottle caps can be used for other purposes such as lottery claiming, product flow tracking, relevant data inquiry, and product identification.
